Comprehensive experiment on characteristics measurement of high critical temperature superconductor

YOU Biao;WU Wei-guo;WU Xiao-shan;School of Physics,Nanjing University;  
Comprehensive experiment of high critical temperature superconductor was designed to investigate the integrated experimental level of college students.Three strip samples were provided,and the contestants were required to quickly find out which one has high critical temperature.A measurement of the temperature dependence of resistance should be subsequently carried out and the critical temperature of the sample should be determined.This paper introduced the contents of the competition problem and its solution,and analyzed the performances of the contestants.
